Well bballad in this life sometimes you have something and loose something else. By give shares and full rights in them with access to marketing and sales people will definately bring you in headache. Most of them when a virus warning will appear would press cancel instead of read the related message of the AV product warning them about the virus. And do not tell me that you will train sales and marketing people...lol....well at least if you have centralized managed AV product at least you would know who is doing and what.

P.S and yes I know what are hidden shares..but worms tend not to touch them
